Every project has a cycle length. When it is reached, the project matures: your holding closes and its value is paid into your wallet as one transaction.
What you receive
The payout is the current value of your holding at maturity — your principal plus or minus how the farm performed across the cycle, within the return cap.
Where capital-back terms apply
Some projects carry a capital-back guarantee. On those, if the holding value at maturity is below your original principal, you are paid the principal instead. It is a floor, not a top-up above principal. The project page states whether this applies.
After maturity
The funds sit in your wallet. Withdraw them, or choose a new project. The matured holding stays visible in your history with its final result.
